Hey! sorry for the late reply again, got back from vacation a few days ago. Anyway, Great news! While cleaning both the IAC valves didn't do much to fix the problem, replacing them and the coolant temperature sensor and setting the timing fixed my idle! no more pops, no more shakes, no more 1800rpm idle, it idles great now! I'm not sure if the coolant sensor had any issues or not but I've heard they're problematic so I figured I'd replace it anyway since they're pretty cheap and would probably save me a headache later on. Thanks for the help, everyone!
